CHURN.

SPECIFICATION forming part of Letters Patent No. 501,806, dated 'July18,1893. Application filedjlpril 29, 1893. Serial No. 472,383. (Nomodel.)

'following is a specification.

This invention has for its object to provide a new and improved churn,wherein an oscilrlating box is provided with compensating springs Theinvention consists in the features of construction and the combinationor arrangement of parts hereinafter described and claimed, referencebeing made to the accompanying drawings, in which- Figure l is a sectionof my improvement on line fr, Fig. 2. Fig. 2 is a top plan view of thesame. Fig. 3 is a side elevation of the same.

A represents the sill or base of the frame; B upright posts upon the topof which the box C is suspended.

a, a, represent cross ,rails securely attaching posts B, B, together toform a rigid frame'.

D represents gudgeons journaling in bearings b, and rigidly attached tothe box C.

c represents pivots preferably secured to the bracket N, on the box soas to hold them rigidly in position.

CZ represents rods'provided with eyes journaling on the pivots c. O, O,represent compensating springs secured to said rods d.

g represents a guide rigidly secured to posts B, and pierced with holesat either end through which the rods d freely move, and serve as theupper seats for thesprings O.

P represent nuts screwed on the lower ends of the rods d for securingand adj usting` the tension of the springs O, O.

I represents a lever; I Vhave show n it of bail form, but this isimmaterial, by means of which the box C is oscillated by the operator.

The interior of the churn is provided with a series of rounds G securedin the slats I-I and located equidistant from the axis of oscillation;these serve as break-rods to separate the cream and break it up in smallsprays as it is thrown from one side to the other.

J represents the lid of the box secured by clamps K.

' It will be apparent that the greater the load the greater the powerengendered by the weight and' force of the moving charge within the box,and consequently a greater depression upon the spring thus acted upon,and the greater the power utilized in the recoil of the springthrowingit back and assisting to move the load in the oppositedirection; hence a comparatively large charge is operated upon almost aseasily as a small charge, due to the use of this compensating spring.

Having described my invention, what I claim is- V1. rlhe combinationwith the oscillating box, of the rods d arranged on opposite sides ofthe axis of the box and provided with adjustable nuts P, a seat g, andcompensating springs O interposed between the seat and the Vnuts on therods, substantially as kdescribed.

2. The combination with the posts B, and the oscillating box C providedwith gudgeons D, of the bracket N having pivots c at opposite sides ofthe gudgeons, the rods d engaging the pivots of the bracket, andprovided with adjustable screw nuts P, the spring seat g secured to oneof the posts, and the cornpensating springs O arranged on the rodsbctween the spring seat and the nuts, substantially as described.

In testimony whereof I have hereunto set my hand.
